So far theres a couple things i have yet to address that are easy fixes such as longer springs on bed level adjust to keep tension on and allow to adjust up another 1mm towards nozzle and i need to mod the filiment feeder to include a guide to feed better.

I have had the odd print issue of part way into a print it seems to continue printing 10mm over from where it should be as in it prints the part still but in the wrong spot but at the right level. like cutting an apple in half then sliding the top over a tad.

I was able to print one item about an inch high before it finished the rest of the part in the wrong spot and another part only 4mm into the print it did it but not as far off "about 5mm off" but it was a smaller diameter part.

What could cause more load in this environment enough to throw it a few mm off?

I am currently going to check belt tension and looking into better feeding of filament to eliminate possible drag on the head.

i got weird stuff like that happening when the plastic clips that hold the extruder rods started to slump (probably from heat)…replaced em and it was ok._________________Miles Blow - Julie Pitts

I usually find it happens when the part warps and jams into the nozzle.

It is also likely to happen with too much speed as the torque decreases with speed. As much as you want to go faster it pays to be conservative as one lost step will screw up your entire part.
